v0.7.0

Minor Changes

• a2e5bc9: Add the code-first screenshotDiff helper for PNG visual comparisons, changed-pixel
  metrics, and highlighted diff images. Expose CDP recording quality in stop/status
  receipts and JSON output, including screenshot fallback. Reject frame rates outside
  the supported integer range of 1 through 60 instead of silently clamping them.

Patch Changes

• a2e5bc9: Fix undersized, padded CDP recordings with emulated viewports and Retina backing
  surfaces. Preserve the starting viewport instead of downscaling to 720p, improve
  source image quality, and default to 60 fps with a 60 fps ceiling. Frame delivery
  still depends on the browser; use a lower frame rate for smaller recordings.
